The production of forms within reality appear to occur only within human experience, but this process can be independent of human interaction with reality. This production comes about through the establishment of partial differences and partial equivalences that actualizes a direct relationship between form and content. These forms are made up of parts of reality, which in turn are wholes that are constituted by other parts. Just as there are vertical levels of parts and wholes, there is a horizontal relationship where a part from one form can be applied to another form on the same level. This configuration has the ability to sustain itself as a purely material process.
